However, the adverse effect of paper sludge on the mechanical properties of the produced particleboard is a serious concern.
This study was conducted to evaluate the recycling of paper sludge for particleboard production. The objective of the research was to characterize the mechanical properties and water resistance of particleboard made from paper sludge. Since the bondability of methylene diphenyl diisocyanate (MDI) adhesive with inorganic materials is more than that of urea formaldehyde (Pizzi, 1983, Palardy et al., 1989,Sellers, 1996 and Xiaoqun, 2003), it was used as adhesive in addition to urea-formaldehyde resin.
